[Suse] Configure LDAP server error "is ldapi enabled" from YaST

Suppose you configured your LDAP server (openLDAP) in Suse (which is STILL free after the trial period, you just don't receive updates) via YaST, but unticked the "use ldapi" checkbox.

You'll find out that you can no longer configure it via YaST due to an error "[...] is ldapi enabled?". Unfortunately, you cannot re-enable it via YaST now, but you can still do so via configuration file.

Edit /etc/sysconfig/openldap with a text editor of your choice and set:

OPENLDAP_START_LDAPI = "yes"

then restart the server

sudo /etc/init.d/ldap restart
